Definitions

  • the present invention relates to a solid fuel heating apparatus. More specifically, it is aimed at a heat generator mainly intended to operate by the combustion of solid fuels such as wood, coal, coke, sawdust, etc., but having the advantage of being able to be easily arranged, in addition, for also function by the combustion of liquid fuels such as oils of various origins, without the need to make any modification of the heater to switch from one combustion mode to another, like this has been explained in European Patent No. 0.011.586.
  • Solid fuel stoves or boilers generally have the disadvantage of being uneconomical insofar as an appreciable proportion of their components are not or are imperfectly burnt. This is due to the fact that a significant part of the gases and volatile matter generated by the pyrolysis of fuels escapes quickly into the flue, directly or after a somewhat elongated journey. In addition, the incompletely burnt volatile matter remains in the exhaust fumes in the form of soot, tars, combustible gases which, in addition to a notable calorific loss, are a cause of pollution of the atmosphere. On the other hand, to this regrettable loss of part of the gaseous or volatile components, is added imperfect combustion of the solid components.
  • the present invention proposes, in particular, to remedy these drawbacks.
  • An object pursued by the present invention is therefore the production of a heating device for solid fuels, such as a stove or boiler, capable of burning all of the gaseous, volatile or solid components of said fuels and, consequently, of giving the possibility of achieve significant energy savings taking into account the fact that all the heat potential of said fuels is used.
  • Another objective of the invention is the production of a non-polluting heating apparatus, of perfect continuous operation and with high calorific value.
  • the heating device is notably remarkable in that its hearth comprises a set of superimposed grids and an economiser constituted by a vertical sheath, preferably cylindrical, the top of which is provided with a sealing means , and the base of which rests on the upper grid of said assembly, said sheath comprising, in its lower part, a plurality of exhaust orifices distributed over its periphery, and having, at its base, a diameter less than that of said grid superior.
  • Said apparatus comprises a body or casing 1 having a circular or other cross section and executed in sheet steel, cast iron or any suitable refractory material.
  • This envelope delimits the hearth 2 of the heating device which can be a stove emitting heat by radiation or, as shown in Figure 1, a boiler.
  • one or two exchangers 3 - 3 ' are installed around the hearth.
  • the upper exchanger 3 is, for example, assigned to the production of hot water intended for domestic uses, while the lower exchanger 3 1 is connected to the distribution network of a central heating installation.
  • an orifice 4 capable of being connected, in any known manner, to a smoke duct, is provided at the upper part of
  • the heater is provided with an air intake device (not shown) executed in a manner known per se.
  • a support ring 6 is positioned, resting, for example, on radial gussets 7 rigidly secured to the internal face of the body.
  • This support ring supports a set of superimposed grids, comprising a plurality of grids 8 - 8a - 8b - 8c - 8d - 8e, ..., mounted in superposition and spaced from one another.
  • These grids can be formed by spaced bars ( Figure 2) or by perforated plates ( Figure 3).
  • the openings of these grids have decreasing dimensions from top to bottom.
  • the spacing between the bars forming each of said grids decreases, from the upper grid 8, the bars of which are most widely spaced, to the lower grid 8e, the bars of which are the least.
  • the grids consisting of bars are arranged so that the bars of which each is made up, have a different orientation with respect to the bars forming the other grids.
  • the upper grid 8 is provided with the largest perforations, while the dimensions of the perforations of the underlying grids gradually decrease, up to the lower grid 8e which has the smallest perforations.
  • the grids 8 - 8a - 8b - 8c - 8d - 8e, ..., are carried by a cylinder 9 resting, by its base, on the support crown 6.
  • a grid with bars 9b each grid is integral with an independent cylindrical belt 9a, so that the stacking of the different grids and their belts makes it possible to reconstitute a cylinder comparable to the cylinder 9 of FIG. 1.
  • the grids thus produced are provided with means making it possible to center and wedge them one above the other.
  • These means are, for example, constituted by lugs 9c distributed over the periphery of the cylindrical belt of said grids and realizing the centering and the setting of the superimposed or underlying grid, according to the adopted arrangement of said lugs.
  • an economizer comprising a vertical sheath 10, for example made of refractory steel and preferably having a cylindrical shape.
  • This sheath is removable and, according to the advantageous embodiment illustrated, it rests, by its base, on top of the upper grid 8 which is advantageously provided with means for centering said sheath.
  • These means are, for example, constituted by a centering wall 11 of cylindrical shape, or other shape complementary to the profile of the sheath, welded to said grid, and in which the lower end of the sheath 10 is fitted.
  • the latter In its lower part, the latter has a plurality of exhaust orifices 12 distributed over its periphery.
  • the sheath is provided with at least two stages of exhaust orifices staggered.
  • Each exhaust port 12 is provided with an external deflector 13 oriented from top to bottom.
  • These deflectors are, for example, obtained by cutting strips in the cylindrical wall of the sheath and folding these cut strips towards the outside.
  • the top of the sheath 10 is equipped with a removable sealing means.
  • This means is advantageously formed by a circular loading pad 14 constituting one of the two homocentric elements for closing the upper part of the heating appliance.
  • the second of these elements is constituted by a removable cover 15 having the shape of a circular crown and the central edge of which is provided with two coaxial annular lips 15 1 - 15 "delimiting a circular groove in which the upper edge of the sheath, when said cover is in place, so as to make a leaktight baffle junction.
  • the loading pad 14 comprises, on its underside and at a short distance from its periphery, a centering ring Z4 'fitted into the outer lip 15 "of the cover, when said pad is in place.
  • the diameter of the base of the economizer 10 - 14 is less than that of the upper grid 8 of the set of grids on which said base rests.
  • the reservoir 31 constituting the lower exchanger has a cylindrical shape and is arranged around the set of grids, while the reservoir 3 forming the upper exchanger also has a cylindrical shape and is placed around the sheath 10, an annular space e being formed between the internal surface of said exchanger 3 and the external surface of said sheath.
  • the set of superimposed grids constitutes the hearth where the complete combustion of solid fuels takes place, while the annular space e forms a combustion chamber for gaseous or volatile components.
  • This combustion cycle is renewed each time the sheath 10 is refilled.
  • this heater can be very easily arranged to be able to operate both with solid fuels and with liquid fuels.
